The deterministic rotation of magnetization by electric fields is a challenging issue for future low-power spintronics. In a Co/0.7Pb(Mg1/3Nb2/3)O3-0.3PbTiO3 multiferroic heterostructure, piezostrain-mediated, macroscopically maneuverable, and non-volatile magnetization reversal without an applied magnetic field is demonstrated. This, combined with the presented phase-field simulations, is of practical relevance for designing prototype devices.
电场控制磁化的确定性旋转是未来低功耗自旋电子学的一个挑战。在 Co/0.7Pb(Mg1/3Nb2/3)O3-0.3PbTiO3 多铁异质结构中，证明了在没有外加磁场的情况下，通过压应变介导的、宏观上可操纵的和非易失性的磁化反转。这一点，结合所提出的相场模拟，对于设计原型器件具有实际意义。
